During rock excavation it is sometimes necessary to stabilize rock massif. As injection aid, Intraplast Z* will allow producing high quality rock bolt grout.

When shotcrete as preliminary rock support, concrete lining will take place. Because water flowing through those concrete structures may contain sediment or flowing with high speed, it is necessary to produce high quality concrete.
